"Schweitzer's great work is probably the most important single contribution to the notable increase in the appreciation and
understanding of J.S. Bach in recent years. Equally valuable aesthetically and practically, it reflects the wide outlook
on life and art which the remarkable calibre of its author's mind makes possible, treating its subject from the standpoint
not of a single art, but of art and science in general." -- Provided by publisher
